METHOD AND DEVICE FOR LAYING CORRUGATED PIPE IN LARGE-DIAMETER PIPELINE |
摘要 |
FIELD: pipeline transport. ^ SUBSTANCE: method comprises connecting the drawing rope to the front face of the corrugated pipe and generating pulse pressure in the inner space of the corrugated pipe. The back face of the corrugated pipe is set in motion by means of an additional rope that connects it with the front face. The central opening of the head of the corrugated pipe receives the slide valve provided with the arrester of axial stroke. The rope for drawing is connected with one end of the slide valve. The additional rope connects the other end of the slide valve with the back face of the corrugated pipe through the control unit. The back face is covered with the pressure-tight lid having a connecting pipe for pressurizing. ^ EFFECT: reduced force for drawing. ^ 2 cl, 1 dwg |
